ROMERO, Adriano L.; BAPTISTELLA, Lúcia H. B. y IMAMURA, Paulo M.. Absolute configuration of some dinorlabdanes from the copaiba oil. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.6, pp. 1036-1040. ISSN 0103-5053. http://dx.doi.org/10.1590/S0103-50532009000600006.
A novel ent-dinorlabdane (-)-13(R)-14,15-dinorlabd-8(17)-ene-3,13-diol was isolated from commercial copaiba oil along with two known dinorlabdanes. The absolute configuration of these dinorditerpenes was established for the first time through synthesis starting from known (-)-3-hydroxycopalic acid, which was also isolated from the same oleoresin.
